Job Description
Founding and early-stage software engineers building AI-native products, platforms, and production systems. Working end-to-end with founders across venture-backed startups.
Responsibilities:
- Own products, features, or core systems from initial concept and architecture through production deployment
- Build across the stack, including backend services, APIs, data infrastructure, frontend/product surfaces, and cloud systems
- Develop AI-native products and workflows using LLMs, agents, tool integrations, retrieval systems, and modern AI development tools where relevant
- Make pragmatic architecture and product decisions in environments with limited process and incomplete requirements
- Work directly with founders, customers, and other stakeholders to identify problems and translate them into shipped software
- Build integrations with external APIs, business systems, data sources, and third-party platforms
- Establish engineering patterns, tooling, testing, observability, and best practices as teams scale
- Help shape engineering culture and, in some roles, mentor or lead engineers who join after you
Requirements:
- Strong professional software engineering experience with evidence of shipping production systems
- Ability to move from an ambiguous problem to a working production solution without requiring a detailed specification
- Strong backend, full-stack, product engineering, or systems engineering fundamentals
- Experience with one or more modern production languages such as Python, TypeScript/JavaScript, Go, Java, or Rust
- Comfort working across multiple layers of a product
- High agency, strong problem-solving ability, and comfort operating in fast-moving environments
- Track record of meaningful technical impact, rapid growth, entrepreneurial work, strong startup experience, or other clear signals of engineering excellence
- Clear communication and ability to explain technical decisions and tradeoffs
- Experience as a Founding Engineer, Early Engineer, Product Engineer, Full-Stack Engineer, Backend Engineer, or Staff/Senior Software Engineer
- Experience at an early-stage or high-growth startup, or ability to operate effectively in a startup-style environment
- 0-to-1 product or platform development experience
- Production AI/LLM or agentic-system experience
- Python and/or TypeScript/React experience
- API integrations, distributed systems, data infrastructure, or developer tooling experience
- Daily use of modern AI coding tools such as Claude Code, Cursor, Copilot, Codex, or similar tools
- Entrepreneurial experience, meaningful side projects, open-source work, or previous founder experience
